Are you using the RSS feed widget or are you trying to post it some other way. To be honest RSS is in the advanced section because it can be difficult. The last time I did one, the RSS widget and the website had incompatible instructions and the team had me do something else entirely. I would suggest for that, making a contact us report and asking them how to make it work.
HTML boxes here are called rich text widgets and you can find those in the advanced section of the menu as well.
Sorry no one answered you. Those are hard questions for most members.
